PAPERLESS_CONSUMER_ENABLE_BARCODES=true + DELETE_PAGES=true live auf mDock, parallel in m/paperless docker-compose.yml (Source-of-Truth) committet (siehe m/paperless commit 8c1ca3f). Neu: - infra/paperless/generate_separator.py — Code-128 PATCHT-Generator (uv inline-deps) - infra/paperless/separator-patchT.pdf — druckbare Trennseite - docs/strategy.md — neuer Abschnitt "Multi-page scan + automatic splitting" Test 2026-05-16: Stapel aus 3 Fake-Schreiben (2 + 1 + 1 Seiten) mit PATCHT-Separator dazwischen → 3 getrennte Paperless-Dokumente mit korrekten Seitenzahlen, Trennseiten entsorgt. Test-Dokumente wieder gelöscht. Closes: nichts (m schliesst Issues selbst — Label "done" via API)
